Quotes (1NF/2NF/3NF)^ru:

Every row-and-column intersection contains exactly one value from the applicable domain (and nothing else). The same value can be atomic or non-atomic depending on the purpose of this value. For example, “4286” can be

• atomic, if its denotes “a credit card’s PIN code” (if it’s broken down or reshuffled, it is of no use any longer)
• non-atomic, if it’s just a “sequence of numbers” (the value still makes sense if broken down into several parts or reshuffled)

This article explores the standard methods of increasing the performance of SQL queries involving the following types of fields: string, date, simple list (in the $LB format), "list of <...>" and "array of <...>".

How can I export project with CSP pages in it? The Atelier export wizard does not include the CSPs in the export list.

Hello,

I'm currently exploring alternatives to CSP/services and ODBC/Sql Maps for access to Caché. I'm not seeing a library which would interest me, so am considering creating one myself.

Does 'CacheConnection' in C# use RPC of some sort, or a defined protocol to communicate with Caché, or does it do so over telnet with scripted commands? I would assume the former. If so, is this a publicly documented protocol that can be implemented by library developers?

Any guidance in this area would be appreciated.

Hi Community!

Check the new video on the. InterSystems Developers YouTube Channel:

Many Data Sources - One Application

hi

    I restored one database on Server B with EXTSELCT^DBREST command from   backup file (this backup file is taken from Server A).  

When I execute select some rows from one table,  it return error like this, 

the same select sql can return correct data  in server A

But when I select other rows from same table on Server B, it return correct data.

Why? maybe the backup file corrupted?

Thanks

I have a stored procedure like below:

Call USER.SP('select * from Sample.Person where SSN='aaaaa'','0','S')

How could I escape the single quotes for aaaaa? I try double single quotes but in vain.

Thanks you.

"SELECT  %SYSTEM.SQL_TableExists('table name') "could work as expected under SQL shell,

but for   "CALL %SYSTEM.SQL_TableExists('table name')" does not work (not any error reported, it just show nothing).

Is there any reason why CALL could not be applied to a stored procedure?

Thanks.

I needed to pass through a file with Ensemble but the operation wasn't writing some filenames as given because the  EnsLib.File.PassthroughOperation 'sanitizes' filenames removing characters that are not valid on some operating

Oh No! It has stripped out my semicolon and ampersand! I need them!

hi

  I execute sql from Terminal

SET result=$SYSTEM.SQL.Execute("SELECT TOP 5 name,dob,ssn FROM Sample.Person")

but I got error "<METHOD DOES NOT EXIST> *Execute,%SYSTEM.SQL"

Why?

Thanks

Hi,

we are trying to use Atelier and GitLab for our Software-development. Our Software has round about 1000 classes that got developed over years.

What we want to achieve is that one repository holding the complete code of one namespace. We also want to create branches to develop new small parts.

The main problem is that Atelier don't have the project view like in Studio where you can add/remove code and have an overview  of the project. It's like viewing the Namespace-Tab in Studio.  The complete source is always present in Atelier.

Hello. I am a student from Syktyvakar Forest Institute(Russia). 

I need to make Research : "Databases for working with spatial data
Consider MySQL, PostgreSQL and 1 to choose from". I want to explore Cache with subject library of spatial data.

Help.

Does Someone from the developers write the libraries of spatial data?

Caché offers a number of methods for going through a collection and doing something with its elements. The easiest method uses a while-loop and lets you fulfill the task in an imperative manner. The developer needs to take care of the iterator, jumping to the next element and checking if the loop is within the collection.

 But is it really what a developer should be concerned with?

Hi

Has anyone worked out any tricks to overcome this issue in 2015 and IE11 where the Dialog content is masked. I'm trying to fix it in a custom one, but you can see that the same issue is happening in the Standard Color Selection one as well.

Hi everybody, 

I have to create a pivot that shows the result comparing the last week of the current date with the last week of the last year in the same month. I tried using the function LAG, but didn´t work.  Works only if I want to compare the months between the two years.  If someone has some idea, i will appreciatte a lot. 

Thanks.

Good day, I have this issue. I have global like: ^myglobal(varX) = $LB(var1,var2). I need to delete all globals that have variable var1 in that list same without a need to iterate through all globals and checking their value.

Exact example:

- in database exist following:

^myglobal("Marek") = $LB("code2",1400)
^myglobal("Ondrej") = $LB("code1",12)
^myglobal("Nikita") = $LB("code2",32)
^myglobal("Evgeny") = $LB("code1",76)
^myglobal("Maks") = $LB("code2",99)
^myglobal("Eduard") = $LB("code1",14)
Now! How to delete all globals that have in list in the first place value "code2" please?

I know this may sound like sour grapes, but really it is not.

I hear all the exciting things about the up coming InterSystems Conference, and I am sure it is.

But it is way, way out of my price range, and I am sure out of the price range of most of the Cache/MUMPS developers, without company backing.

Just wondering what others think.

Is there an available API for creating a business service? Is it just a table that Business Service Wizard is inserting the data into or it is something more? 

Good day, I would like to find out the size of Caché ObjectScript variable in order to guarantee that my program will not leak, equally in terminal and Caché globals.  For example how huge number I can store in that variable ? And what happen in Caché when variable will leak ? How is this behavior treated? (how much memory is reserved for common variable?)

Thanks  in advance for your answers.

How do we generally create an error object of %Status?

Set status=$SYSTEM.Status.Error($$$GeneralError,"Something went wrong")

Now, like $$$GeneralError there are many more macro defined within %occErrors include file by Intersystem which we can use.

i.e.

In my cache studio i couldn't find the a namespace of iknow so how can i check is my studio version is compatible to to the one i am using now. If i don't have one then can be able to create a new namespace in studio?

Hi.

It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:

set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")

set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr

How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?

I've tried

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map from %Library.Array instance to %Library.

Hi, we are trying to deployed a changed schedule to our DEV instance (from our TST).  And are getting an error:

Dear All,

I would like to block ADT_A18 and ADT_A47 HL7 2.3 messages with an empty MRG:1 field.

This is to prevent my current HL7 ADT router (Business process) sending blank Merges downstream.

I've attempted to create a business rule where this would return out the business role process.  However the messages still loop though the other rules.

Any advice would be great.

Kind Regards

Stuart

Hello...

I need to convert a array  (JSON) in a List Of String. I think, there is some method that does it directly.

Something like that:

SAMPLES>set list = ##class(%ListOfDataTypes).$fromJSON("[""a"",""b"",""c""]")

%FromObject+21^%Library.RegisteredObject.1 *%Exception.General Compose Compose %FromObject Unable to map frm %Library.Array instance to %Library.ListOfDataTypes

I have reading about this but I don't found some trick to help me.

Thanks!!

I have a class with text property, which contains html text (usually pieces, so it may be invalid), here's a sample value:

<div moreinfo="none">Word1 Word2</div><br>
<a href = "123" >Word3</a>

When I add iFind index on text, there are at least two problems:

• Words like moreinfo="none">Word1, so exact match with Word1 returns nothing
• Irrelevant results for href search

How can I pass plaintext into iFnd index?

Hi Community!

Please find the Developer Community video of the week:  

Monitoring : Don't Turn a Drama into a Crisis 

Sometimes, it comes in very handy (especially for the EAV model) to use array properties in a class and be able to qickly search by their elements: both the key and the value.

Let’s take a look at a simple example:
